HOSE-COUPLING.-

SPECIFICATION formingpart Of Letters Patent NO. 685,014, dated October22, 1901. I

Application filed April 2, 1901. Serial No- 64,024. (No modeL) To allwhom it may coll/corn.-

' Be it known that I, SENECA H. THRESHER,

a citizen of theUnited States, residing in Norwich, in the county of NewLondon and State of Connecticut, have invented certain new and usefulImprovements in Hose-Couplings, of which the following is aspecification.

This invention relates to coupling devices for securing sections of hosetogether and for IO attaching fittings, &c., to hose, and has for.

an object to provide a simple and eflieient device ofthis character andone which may be readily applied to its intended purpose.

In the drawings accompanying the present specification, Figure 1 is aperspective view of the end of a section of hose, showing a deviceembodying the present invention used for the connection of a fittingthereto. Fig. 2 is a cross-sectional View of the parts connected .andthe device shown in Fig. 1, this figure being upon a somewhat largerscale than that to-which Fig. 1 is drawn. Fig. 3 is a perspective viewof a modified form of the coupling device.

Similar characters of reference designate corresponding arts in all thefigures.

The device of the present invention embodies, essentially, an expansibleand contractible curved band adapted to encircle the hose and by itscontraction to clamp the same to the fittings, &c., which it is desiredto connect to the end of the hose. This encircling band is of anyappropriate form and material-thus, for instance, it may be a simplewirebent to a substantially circular form, as shown in Figs. 1 and 2, inwhich figures the band is designated by B, or the encircling band may bea flattened strip B, as shown in Fig. 3. An application of the device isrepresented in a generaltway in Fig. 1, the end 20f a hose lengthbeingindicated and in which is inserted a fitting 3, represented as apipe length, which, for instance, may be utilized for connecting thelhose 5 length to a secondlength. By forcing the two I ends of theencircling band from each other there evidently results a contraction ofthe circle formed by the band, tending to compress the hose andeifecting the clamping of the same to the fitting. This movement and anopposite or releasing movement of the band ends are convenientlyaccomplished by securing to one end of the band a reaction block orfixture C and mounting in the same suitable means for moving the otheror free end of the band. This means ad vantagconsly consists of a screw,and the fixture is here shown as provided with a screw D, which euters atapped hole in the fixl ure and impinges against the end of the band. Inthe form of the device shown in Figs. 1 and 2 the end of the bandsecured to the fixture is bent over uponitself and enters an openingprovided for itiu the fixture, such construction securely holding thetwo together, while the correspondingly bent free end portion of theband enters a socket or recess 4 in the end of the screw, by which meansthe ends may be forced apart and the circle of the band contracted. Ifthis latter is made of elastic material, a rotation of the screw in theoppo-- site direction permits the expansion and consequent enlargementof the circle inclosed by the band.

In the form shown in Fig. 3 and in which the band is also assumed to beof an elastic material the screw D impinges against .the outwardly-bentend of the band, being preferably seated in a recess therein. The screwin both instances is suitably constructed to facilitate itsmanipulation, the screw of Figs. 1 and 2 being shown as having a squaredend 5, while in Fig. 3 it is provided with a thumbpiece 5'.

Having described my invention, I claim 1. A hose-coupling comprising aclampingba'nd bent to form substantially an overlapping circle of oneconvolution, with the opposite ends lying side by side, in combinationwith a fixture separate from and rigidly secured to one end of the band;and a screw engaging with a tapped hole in the fixture and impingingagainst the opposite end of the band for forcing the two ends apart andthereby cause a contraction of the inclosed 5 area, one contactingsurface being formed with the socket to receive the part which enandwhich is provided with means for facili gages with it. tating itsmanipulation.

2. A hose-coupling comprising an encir- V cling band made of an elasticmateriah in SENECA H H 5 combination with a fixture secured to one endWitnesses:
